Riboswitch aptamer structures. The consensus secondary structure models based on expanded
riboswitch sequence alignments are depicted according to the symbols defined in the
inset. Each structure is further annotated with RNA structure motifs and the statistical
significances (p values) of the mutual information scores between base-paired alignment columns. New
predictions of interacting bases from the MI analysis are numbered and indicated by
asterisks. More detailed descriptions of these predictions are provided in Figure
7.
